INVENTOR. ANTHONY J. QUBE RA United States Patent f 3,124,055 WINDOW VENTILATOR Anthony J. Rubera, 483 Woodbridge St, Manchester, Conn. Filed Nov. 29, 1962, Ser. No. 241,000 2 Claims. (Cl. 98-99.5)

This invention relates to draft deflectors for windows which may be adjustable over a wide range to fit window frames of different widths.

An object of primary importance is to provide a draft deflector for windows enabling windows to remain raised during inclement weather to maintain ventilation without subjecting the room to an undue flow of air through the open window, the deflector also being adapted for prompt insertion and removal to and from the window frame.

Another object of importance is to maintain the alignment of the two relatively adjustable members of the ventilator in all adjusted positions so that the unit Will be rigid throughout its length.

With the above and other objects in view, the invention includes the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing.

In the accompanying drawing annexed hereto and forming a part of this specification, I have shown the invention embodied in forms of ventilators for conventional window frames, but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing:

FIG. 1 is a perspective view of a window ventilator or draft deflector made in accordance with the present invention;

FIG. 2 is a similar view of another embodiment of the invention;

FIG. 3 is a cross sectional view taken on the plane of line 3-3 in FIG. 1;

FIG. 4 is a cross sectional view taken on the plane of line 4-4 in FIG. 2, and

FIG. 5 is a perspective view of another embodiment of the invention broken away to show alternate means for retaining the adjustable panels in adjusted position.

In the above mentioned figures of the drawing, there have been shown two embodiments of the invention, but it is to be understood that changes and modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

Referring more in detail to the figures of the drawing and first to the form of the invention shown in FIG. 1, it will be seen that the draft deflector comprises two relatively adjustable panel members and 12. These members may be made of suitable sheet or molded material such as Plexiglas, plastic, etc., preferably transparent, and having their outer ends bent at right angles to the panel as shown at 14 and 16 respectively.

One of the panel members 10 has one face thereof provided with one or more elongated dovetail grooves 18 extending lengthwise of the panel. The other panel 12 is provided with one or more dovetail projections adapted to interengage with the dovetail grooves 20 of the first panel. By means of these projections and grooves, the

3,124,055 Patented Mar. 10, 1964 panels may be adjusted lengthwise by sliding movements, the panels at all times and in all adjustments being maintained rigidly in alignment.

The panels 10 and 12 each has an angular end portion 1 and 16 bent as shown in the figures of the drawing to engage against the inner surface of a window frame. In these end portions 14 and 16 there may be provided openings 22 for suitable screws or nails. For convenience in positioning and removing the ventilator, short outstanding projections 24 may be provided having their heads embedded in recesses in the material of the panels. The points of these projections 24 may be forced into the material of the window frame to retain the panels in place by forcing the panels apart to permit the end portions to firmly engage the window frame member.

FIG. 2 shows a modification in that a third panel mem ber 26 is interposed between the panels 10 and 12 shown in FIG. 1. In this form of the invention, the adjustment of the ventilator may be greatly increased. The intermediate member 26 as shown is provided with dovetail grooves 28 extending the full length of the member 26 on one face. On the opposite face are provided projections 30.

Preferably, member 26 has its grooves 28 and projections 34) so disposed that these grooves 28 and projections 3%) will inter-engage the grooves 18 and projections 20 of panels 10 and 12 respectively. In this disposition of the grooves and projections an intermediate panel 26 may be used with panels 10 and 12 without alteration.

In FIG. 5 the panels 32 and 34 are retained closely adjacent each other but relatively adjustable by magnetic means. One of the panels 32 has spaced magnets 36 molded therein along its length. The other panel 34 is provided with an elongated strip of steel 38 preferably embedded in a dovetail groove and adapted to contact the exposed surfaces of the magnets 36. Preferably the magnets 36 may be formed of Alnico or other highly magnetizable material to retain the panel 34 having the strip of steel 38 forming an armature for the magnets 34 firmly in contact with the strip 38. As shown in this figure, the outer surfaces of the magnets 36 and strip 38 are flush with the contiguous surfaces of the panels 32 and 34.

I claim as my invention:

1. A window ventilator comprising two relatively adjustable panels,

said panels being formed integrally of a single sheet of molded plastic material and having an end portion thereof bent at right angles to the main portion of said panels,

interengaging grooves and projections on said panels extending lengthwise of said panels to permit lengthwise adjustment thereof,

and intermediate panel having grooves extending from end to end on one surface thereof and projections formed on the opposite surface thereof extending from end to end,

the grooves and projections on said intermediate member being adapted to engage respectively the grooves and projections on said first mentioned panels,

and means to detachably attach said end portions to a window frame.

2. A window ventilator comprising two relatively adjustable panels having their ends bent at right angles to each other to fit between the end surfaces of a Window frame,

spaced magnets moulded within one panel,

and an armature member embedded within the other panel,

the outer surfaces of said magnets and strip being in contact in any adjustment of said panels.
